Beam load

 

Overview

IMG_C_ICON_DOT.gifConcentrated and distributed force(moment) can be applied with reference to the GCS or the beam element coordinate system. Linear beam load can be used when multiple beam elements are connected continuously. Both ends of the beam element can be specified and a continuous beam load can be applied as either a distributed load or force load. The load can also be applied to a continuous beam placed in a curve on the same plane as the loading direction. For a beam element load, the beam load is applied as a distributed or force on the singular beam element.

 

Methodology

[Object]

For beam elements, select the beam element directly or select the line used to create the element to apply a load. For continuous beam loads, the On Load Application Line Method or Select Element Method can be used.

The [On the Loading Line] command applies the load to elements placed on the line between the two points used to specify the continuous beam load. In this case, selecting two nodes sequentially inputs the load for elements existing on the line between the two points. For the [Selected Element] command, the load is applied to the selected element. It can be used to apply the continuous beam load on elements that are not placed on the line. Select the start and end points of the beam element on which the load will be applied.  

[Direction]

The direction can be set with reference to the global coordinate system (X,Y,Z) or element coordinate system (x,y,z). The projected area can be additionally set, which specifies whether to apply the load on the total beam element within the load application section, or to apply the load by the projected length, perpendicular to the load application direction. This option is only valid for [Distributed] loads in directions with respect to the global coordinate system (GCS).  

[Value (Fraction/Length)]

  • Fraction: Input the continuous beam load position using a relative length ratio of the load application section.

  • Length: Input the actual length as the reference for the continuous beam load position.

x1 and x2 are the start and end points of the beam load respectively and w1,w2 are the load size at points x1,x2. Entering a negative load size applies the load in the opposite direction to the set direction, and a linearly distributed (increment, decrement) load can be set using the size difference.
